Question

I'm new to iOS, my question is: What is the best way to pass data from one UIViewController to another, through singleton class or *.h file?

1) use properties to pass data.

- (void)someMethod {
  MyViewController * vc = [[MyViewController alloc] initWithNibName:"MyViewController" bundle:nil];
  vc.someData = data;
}

Also if you use Segues you should do it prepareForSegue method

-(void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
    MyViewController *vc = segue.destinationViewController;
    vc.someData = data;
}

you can pass a singleton this way if you want. vc.someData = [MyDataStorage sharedInstance]; – Kostiantyn Koval Apr 09 '14 at 12:23

we can pass data through public property, then why we are using protocol – RameshKumar Selvam Jun 13 '14 at 09:37
